I'm on valcyte about a month now & my insomnia &anxiety is a lot worse. I also get woken by severe heart palpitations (feels like banging in my chest). I stopped it a week ago bec of various other side effects but the insomnia & palpitations are getting worse. (Took 2 small doses of lexapro but those didn't agree w me) I read another thread that said valcyte can act like a stimulant; is that accurate? And how do I get rid of these side effects?
